Nope, stock uca's. I keep wondering the same thing, if it'll ride better with aftermarket units.
I don't know that the UCA makes that much of a difference. I replaced mine with the Nitros. But, that was because my UBJs were absolutely shot and needed to be replaced.
The thing that WILL make a difference (and I think EVERYONE should get them with any lift) are the extended links from Jason for the front and rear swaybars. I didn't do them at first. Truck rode fine. Got them a few months later. Truck rode noticeably better both on and off road.
